EDWARD ADAMSON, OF PROVIDENCE, RHODE ISLAND.

V 7 REED FOR LOOMS.

SPEGIFICATiON forming part of Letters Patent No. 223,974, dated February3, 1880.

Application filed April 24, 1879.

To all whom it may concern:

Be it known that I, EDWARD ADAMSON, of Providence, in the State of RhodeIsland, have invented certain new and useful Improvements in Feeds forLooms; and I do hereby declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it ap pertains to make and use the same, referencebeing hadto the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

My invention relates to improvements in reeds for weavers use; and itconsists of a reed provided with double springs arranged to telescopeone within the other, in combination with dents and means for holdingthe same, all as will be hereinafter more fully described, and pointedout in the claims.

. In my drawings, Figure 1 is an elevation of my improved reed with oneofthe tubes broken away to show the coils and dents in their relationsto each other. Fig. 2 is a transverse section on line as a; of Fig. 1.

Similar reference-letters indicate like parts in all of the figures.

Referring to the drawings, a a are the metal dents, without slots or anyextra finish at their ends. b b are wire coils capable of expansion andcontraction, which hold the ends of the dents a a in fixed positions.

A A are open tubes, which form casings to the coils b b and assist inkeeping said dents in position against lateral movement.

On either end of the reed are bars 0 0, provided with cylindrical ends01 d, adapted to slide into the open cylinders A A and fit against thecoils b b. The purpose of these bars is twofold: first, to hold thedents a a in given positions inv relation to each other within thecoils, and, secondly, to fill up the spaces outside of the dents andform guards to prevent the shuttle from jumping from its race throughthe said spaces when the said dents 5 are properly adjusted to suit thewarp.

cylindrical ends 61 d of the bars 0 a, small linchpins 'or other simplemechanical appliances are to be provided, to prevent the bars 0 c fromyielding to the pressure of the coiled springs incased within the tubes.The bars 0 0 may be of any number or size consistent with utility, andare readily adjustable inincreasing or diminishing the number perinoh ofdents and spaces in the reed. The bars 0 may be of metal or any suitablematerial.

This arrangement of a coil within a coil is simple and compact, doingaway with the necessity of slots in the dents, which are essential whenbars are used with interlacing coils, as shown in a patent granted to meof recent date, No. 212,120.

The tubes which incase the coils are about the size of the ordinaryreed-ribs, and when in place the edges of the tubes forming theiropenings bear against the edges of the dents, to prevent, as beforementioned, said dents from moving laterally within the grasp of saidcoils.

By the use of open tubes in combination with telescoping coils I efi'ecta simple construction to my reed much to its advantage, gaining therebyprotection to the springs and stiffness to its general construction.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In aweavers reed, the double springs 12 1), arranged to telescope theone within the other, in combination with the dents a and means,substantially as described, for holding the same, as and for the purposeset forth.

2. In combination with the double coilsprings b b, one within the other,and dents a, the open tubes A A, as specified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
